A Quote by Barack Obama

The hard truth is carbon pollution has built up in our atmosphere for decades now. And even if we Americans do our part, the planet will slowly keep warming for some time to come.
Science is warning us that if we do not quickly reduce the global warming pollution that is trapping so much of the heat our planet normally radiates back out of the atmosphere, we are in danger of creating a permanent 'carbon summer'.
If there is no cost to be paid for the indiscriminate dumping of pollution into the earth's atmosphere, then it should be a surprise to no one that today we will dump another 70 million tons of global warming pollution into the thin shell of atmosphere surrounding our planet. ... We have to [act] this year, not next year. Mother Nature does not do bailouts.
When you buy carbon offsets, you pay to take planet-warming carbon dioxide out of the atmosphere in exchange for the greenhouse gases you put in. For example, you can put money toward replanting trees, which absorb carbon dioxide from the atmosphere.
Today, about 40 percent of America's carbon pollution comes from our power plants. There are no federal limits to the amount those plants can pump into the air. None. We limit the amount of toxic chemicals like mercury, and sulfur, and arsenic in our air and water, but power plants can dump as much carbon pollution into our atmosphere as they want. It's not smart, it's not right, it's not safe, and I determined it needs to stop.
Humans have obviously contributed a great deal of carbon to the atmosphere. So we are warming the planet up.
If we have come up with a creative decision and somebody comes up with another idea, you do have to get into the depths of it and ask: "Is it a better idea? Or is it a different idea?" That can be hard. But that's the type of conversation the director and I will have, or as part of our creative groups. So with that in mind, it's hard to keep a budget in line. It's like in life, if you've ever built anything for the first time you're usually better at it the second time.
The Keystone pipeline will spew a massive amount of carbon pollution into our fragile atmosphere. It should be stopped.
Our planet is warming due to pollution from human activities. And a warming climate increases the likelihood of extreme weather.
Decades of scientific research has proven that carbon pollution is harmful to human health and causes global warming.
Pollution from human activities is changing the Earth's climate. We see the damage that a disrupted climate can do: on our coasts, our farms, forests, mountains, and cities. Those impacts will grow more severe unless we start reducing global warming pollution now.
We have to reenergize our economy so it works for all Americans; invest in our schools so that all our children have the tools they need to compete and succeed in life; rebuild and enhance our infrastructure; and we must reduce carbon pollution and reverse climate change.
And yes, my plan will continue to reduce the carbon pollution that is heating our planet - because climate change is not a hoax. More droughts and floods and wildfires are not a joke. They're a threat to our children's future. And in this election, you can do something about it.
Even as our unwitting alterations to Earth's carbon and hydrological cycles slowly make storms more damaging, our ability to monitor our planet from space and make reliable short-term forecasts have equipped us enormously to withstand them.
Anything greater than 350 of parts of carbon dioxide per million is more than the planet can safely deal with. It is what's overwhelming our climate system. Because we've been going up about three parts per million per year. And eventually, we will always be above 410, and then above 420, and above 430. We just keep pouring more carbon into the atmosphere.
Strong limits on carbon pollution will save Americans money, create jobs, improve our health, and help defuse climate change.
We need to put a price on carbon, and that's what cap-and-trade does and that's also what a CO2 tax does. As long as our current valuation in the marketplace tells us every minute of every day that it's perfectly all right to dump 90 million tons of global warming into the thin atmosphere surrounding the planet every 24 hours as if that atmosphere is an open sewer, then the individual actions are not going to solve the problem.
